Material Design Lite JS不适用于动态加载的HTML文件 [英] Material Design Lite JS not applied to dynamically loaded html file

问题描述

我想统一我网站的导航布局，所以我创建了一个单独的html文件，其中包含导航代码。我使用JS动态加载文件：

I want to unify the navigation layout for my website, so I created a separate html file that holds the code for the navigation. I use a JS to load the file dynamically:

$("#navigation").load("/navigation/navigation.html", function() {
   $.getScript('/material.min.js');
});

问题在于material.min.js没有为这个动态加载的组件执行HTML和我失去了一些关键的功能。我如何解决这个问题？

The problem is that the material.min.js does not get executed for the dynamically loaded components inside this html and I lose some crucial functionality. How do I fix that?

推荐答案

检查 componentHandler 是否已加载，并尝试升级元素后加载。

Check if the componentHandler is loaded, and try to upgrade the elements after load.

if(!(typeof(componentHandler) == 'undefined')){
  componentHandler.upgradeAllRegistered();
}

组件处理程序的工作方式

How the Component Handler works

总之，这遍及所有注册的组件。使用提供的CSS类查询所有节点。循环播放并逐个实例化它们。在节点上完成升级时，升级的对象将添加到数据集中。此对象包含逗号分隔的组件列表 classAsString 属性，以确定哪些升级已完成。

In short this goes over all registered components. Queries for all nodes with the provided CSS class. Loops over those and instantiates them one-by-one. When the upgrade is done on a node, the upgraded object is added to the dataset. This object contains a comma separated list of component classAsString properties to identify which upgrades have been done.
